php: getting rid of ?p= query in url?

问题:

hey guys, i'm not looking for a mod_rewrite thing or anything related. i'm just not sure if this is possible or not?

i'm using if(isset($_GET['p'])) … to check if ?p=something is set in my url, if not $foo = "bar"; if a ?p= is set e.g. ?p=something –> $foo = "something". got me?

if i manually enter now ?p=bar to my url the string in my url is actually the default one. Because if I don't have a ?p in my url $foo = "bar";

I wonder if that's the case i can get totally get rid of the ?p= part in my url? if the default string is set to my $foo variable i just wanna have a clean url without any distractign ?p=bar in my url.

sorry for the weird foo and bar stuff, i had no better example ;) regards matt

回答1:

if ($_GET['p'] == 'bar') {
        parse_str($_SERVER['QUERY_STRING'], $q);
        unset($q['p']);
        header('Location: ' . $_SERVER['PHP_SELF'] . ($q ? "?" . http_build_query($q) : ''));
}

is a neat way. It does not wipe other GET parameters, if they exist.

回答2:

Is this what you're asking for? (Do a redirect if the default was entered)

if (isset($_GET['p'])) {
  if ($_GET['p'] == $defaultP) {
    header("HTTP/1.1 302 Found");
    header("Location: ".$urlWithoutQuery);
    exit(); // or whatever the function is.
  } else {
    $foo = $_GET['p'];
  }
} else {
  $foo = $defaultP;
}

Note that this must be done before anything at all is sent to the client (as it's part of the header).

As far as I know, the only way to scrub something from the URL on clientside is either a redirect, or javascript (which, in effect, also does a reload, so the redirect is probably a lot faster).

Look at this mod_rewrite tutorial: tutorial

回答4:

Use Apache's mod_rewrite to change example.com/?p=pagename to example.com/pagename

Put this in your .htaccess file:

<IfModule mod_rewrite.c>
  RewriteEngine on

  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteCond %{REQUEST_URI} !=/favicon.ico
  RewriteRule ^(.*)$ index.php?p=$1 [L,QSA]
</IfModule>

Voila, no ?p=

If you want to implement friendly/clean urls, you might want to take a look at Net_URL_Mapper.

Yes. Just get rid of it. It's nobody but you who set these urls on your site. So, edit your site's HTML and get rid of anything you want.
